"&lt;p&gt;&lt;/p&gt;&lt;p&gt; Rob Gronkowski will undergo his fifth surgery since injuring his forearm last season. (Jared Wickerham/Getty Images)&lt;/p&gt;&lt;p&gt;&lt;/p&gt;&lt;p&gt;New England Patriots tight end Rob Gronkowski will undergo another surgery on his back in mid-June, likely sidelining him for a portion of training camp, according to Albert Breer of NFL.com.&lt;/p&gt;&lt;p&gt;The Patriots anticipated Gronkowski would require the surgery after their record-breaking tight end experienced chronic back pain.&lt;/p&gt;&lt;p&gt;Gronkowski has undergone four surgeries on his left forearm since mid-November after injuring it during the 2012 season, then reinjuring it during the playoffs. The infection involved with those surgeries has cleared up, according to a Breer tweet.&lt;/p&gt;&lt;p&gt;Gronkowski previously underwent a 3-1/2-hour microdiscectomy to remove a small portion of his spine and relieve pressure on his sciatic nerve while at the University of Arizona.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;PHOTOS: The fabulous life of Rob Gronkowski&lt;/strong&gt;&lt;/p&gt;&lt;p&gt;https://twitter.com/AlbertBreer/status/339828624754606082\nhttps://twitter.com/AlbertBreer/status/339828849175056384&lt;/p&gt;"^^<http://www.w3.org/2001/XMLSchema#string>
